Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a device for adjusting the angle of a photovoltaic array. Background Technology

[0002] With the widespread application of renewable energy, photovoltaic power generation, as an important method of clean energy utilization, is seeing its application scale continuously expand. A photovoltaic array consists of multiple photovoltaic panels, and the angle at which the photovoltaic panels receive sunlight directly affects the photovoltaic power generation efficiency.

[0003] Currently, most photovoltaic (PV) arrays on the market are fixedly installed, making it impossible to adjust the angle of the PV panels in real time according to changes in the solar altitude angle. This results in low light-gathering efficiency of the PV panels at different times, affecting the overall power generation performance. Although some PV panels can be angled, most PV panels are adjusted individually, making it impossible to achieve synchronous and unified adjustment of the entire PV array. If the overall light-gathering angle of the PV array needs to be adjusted, each adjustment mechanism must be operated individually, which is not only cumbersome and time-consuming, but also makes it difficult to ensure the consistency of the adjustment angle of all PV panels. This leads to uneven light-gathering efficiency of the PV panels in the array, further affecting the overall power generation efficiency. Therefore, we propose a PV array angle adjustment device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for adjusting the angle of a photovoltaic array.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A photovoltaic array angle adjustment device includes multiple bases. A vertical plate is fixedly mounted on the top of each base. A reinforcing plate is fixedly mounted between two adjacent vertical plates, and a control box is fixedly mounted between two adjacent vertical plates, with the control box located below the reinforcing plate. A rotating shaft is rotatably mounted between corresponding two vertical plates. Multiple rotating seats are fixedly sleeved on the rotating shaft. A common mounting bracket is fixedly mounted on one side of two corresponding rotating seats. A photovoltaic panel is mounted within the mounting bracket via a detachable structure. A drive shaft is rotatably mounted on the bottom inner wall of the control box, extending above the reinforcing plate. A drive mechanism for rotating the photovoltaic panel is provided between the drive shaft and a drive shaft.

[0006] Preferably, the driving mechanism includes a driving bevel gear and a driven bevel gear. The driving bevel gear is fixedly installed at the top end of the driving shaft, and multiple driven bevel gears are fixedly installed on the driving shaft, with the driving bevel gear meshing with the corresponding driven bevel gear.

[0007] Preferably, a housing is fixedly installed on the top of the reinforcing plate, and the driving bevel gear and the driven bevel gear are located in the corresponding housing.

[0008] Preferably, two guide rods are fixedly installed on the front and rear inner walls of the control box, and guide seats are slidably installed on the guide rods. The same drive seat is fixedly installed between two adjacent guide seats, and a linkage mechanism is provided between the drive seat and the transmission shaft.

[0009] Preferably, the linkage mechanism includes a rack and a rotary gear. The rack is fixedly mounted on one side of the drive seat, and the rotary gear is fixedly mounted on the transmission shaft. The rack meshes with the corresponding rotary gear.

[0010] Preferably, threaded rods are rotatably mounted on the front and rear inner walls of the control box, and the drive seat is threadedly fitted onto the threaded rods, with a linkage shaft fixedly installed between the two connected threaded rods.

[0011] Preferably, a servo motor is installed on the front side of the vertical plate located at the foremost side, and the output shaft of the servo motor is fixedly connected to the corresponding threaded rod.

[0012] Preferably, a controller is installed on the front side of the vertical plate located at the foremost edge, and the servo motor is electrically connected to the controller.

[0013] The beneficial effects of this utility model are: 1. By setting a reinforcing plate between adjacent vertical plates, the connection stability between the vertical plates and the base is effectively improved, enhancing the overall wind and earthquake resistance of the device and enabling it to adapt to harsh outdoor environments. At the same time, the housing protects the bevel gear in the drive mechanism, further ensuring the stable operation of the device's transmission components and extending the device's service life. 2. By using a servo motor as the driving power source and working with a controller to achieve automated control, the servo motor can precisely control the rotation of the threaded rod. Through the transmission action of the linkage mechanism and the drive mechanism, the power is precisely transmitted to the rotating shaft, realizing the precise adjustment of the photovoltaic panel angle, ensuring that the photovoltaic panel is always at the optimal light-receiving angle, and improving the photovoltaic power generation efficiency.

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0017] This application discloses an angle adjustment device for a photovoltaic array.

[0018] Reference Figure 1-4 A photovoltaic array angle adjustment device includes multiple bases 101. A vertical plate 102 is fixedly installed on the top of the base 101. A reinforcing plate 103 is fixedly installed between two adjacent vertical plates 102, and a control box 201 is fixedly installed between two adjacent vertical plates 102, with the control box 201 located below the reinforcing plate 103. A rotating shaft 104 is rotatably installed between two corresponding vertical plates 102. Multiple rotating seats 105 are fixedly sleeved on the rotating shaft 104. A common mounting bracket 106 is fixedly installed on one side of two corresponding rotating seats 105. A photovoltaic panel 107 is installed in the mounting bracket 106 through a detachable structure. A drive shaft 203 is rotatably installed on the bottom inner wall of the control box 201. The drive shaft 203 extends above the reinforcing plate 103, and a drive mechanism for rotating the photovoltaic panel 107 is provided between the drive shaft 203 and the drive shaft.

[0019] In this embodiment, the drive mechanism includes a drive bevel gear 301 and a driven bevel gear 302. The drive bevel gear 301 is fixedly installed at the top of the drive shaft, and multiple driven bevel gears 302 are fixedly installed on the transmission shaft 203. The drive bevel gear 301 meshes with the corresponding driven bevel gear 302. Through the meshing transmission of the drive bevel gear 301 and the driven bevel gear 302, the power of the transmission shaft 203 can be transmitted to the drive shaft, thereby driving the rotating shaft 104 to rotate and realizing the adjustment of the angle of the photovoltaic panel 107.

[0020] In this embodiment, a housing 202 is fixedly installed on the top of the reinforcing plate 103, and the driving bevel gear 301 and the driven bevel gear 302 are located in the corresponding housing 202. The housing 202 can protect the driving bevel gear 301 and the driven bevel gear 302, preventing external dust, rainwater and other impurities from entering the gear meshing part and affecting the transmission effect. At the same time, it can also prevent the gear from causing injury to personnel when it is running, thereby improving the safety and service life of the device.

[0021] In this embodiment, two guide rods 401 are fixedly installed on the front and rear inner walls of the control box 201. Guide seats 402 are slidably installed on the guide rods 401. The same drive seat 403 is fixedly installed between two adjacent guide seats 402. A linkage mechanism is provided between the drive seat 403 and the transmission shaft 203. The cooperation between the guide rods 401 and the guide seats 402 can guide the movement of the drive seat 403, ensure the stability of the drive seat 403 during movement, avoid deviation, and thus ensure the transmission accuracy of the linkage mechanism.

[0022] In this embodiment, the linkage mechanism includes a rack 501 and a rotating gear 502. The rack 501 is fixedly mounted on one side of the drive seat 403, and the rotating gear 502 is fixedly mounted on the transmission shaft 203. The rack 501 meshes with the corresponding rotating gear 502. When the drive seat 403 moves, the rack 501 moves accordingly. Through the meshing action of the rack 501 and the rotating gear 502, the rotating gear 502 is driven to rotate, thereby driving the transmission shaft 203 to rotate and providing power to the drive mechanism. This linkage method has a simple structure, high transmission efficiency, and easy-to-control adjustment accuracy.

[0023] In this embodiment, threaded rods 601 are rotatably mounted on the front and rear inner walls of the control box 201, and drive seats 403 are threadedly fitted onto the threaded rods 601. A linkage shaft 603 is fixedly installed between two connected threaded rods 601. The threaded rods 601 are used to drive the drive seats 403 to move. Multiple threaded rods 601 are connected into a whole through the linkage shaft 603, so that multiple threaded rods 601 can rotate synchronously, thereby ensuring that multiple drive seats 403 move synchronously, ensuring the consistency of the overall adjustment of the device, and avoiding deviations in the angle adjustment of the photovoltaic panel 107 due to asynchronous movement of some drive seats 403.

[0024] In this embodiment, a servo motor 602 is installed on the front side of the foremost vertical plate 102, and the output shaft of the servo motor 602 is fixedly connected to the corresponding threaded rod 601. The servo motor 602 has the advantages of high control precision, fast response speed and stable operation. It can accurately control the rotation angle and speed of the threaded rod 601, thereby achieving precise control of the moving distance of the drive seat 403, and finally achieving the purpose of precisely adjusting the angle of the photovoltaic panel 107 to meet the requirements of the solar altitude angle change at different times for the light-collecting angle of the photovoltaic panel 107.

[0025] In this embodiment, a controller is installed on the front side of the frontmost vertical plate 102, and the servo motor 602 is electrically connected to the controller. The controller can automatically control the start, stop, rotation direction and rotation angle of the servo motor 602 according to the preset program, so as to realize the automatic adjustment of the angle of the photovoltaic panel 107 without manual operation, which reduces labor costs and improves the ease of use and intelligence of the device.

[0026] In this utility model, when using the photovoltaic array angle adjustment device, the photovoltaic panel 107 angle adjustment program is first preset by the controller. When the angle of the photovoltaic panel 107 needs to be adjusted, the controller sends a control signal to the servo motor 602. The servo motor 602 starts and drives the corresponding threaded rod 601 to rotate. Under the action of the linkage shaft 603, multiple threaded rods 601 rotate synchronously. When the threaded rods 601 rotate, the drive seat 403 moves along the guide rod 401 under the action of the thread of the threaded rod 601. The guide seat 402 slides along the guide rod 401 with the drive seat 403 to ensure the stable movement of the drive seat 403. When the drive seat 403 moves, it drives the rack 501 to move synchronously. 01 meshes with the rotating gear 502, causing the rotating gear 502 to rotate. The rotating gear 502 drives the transmission shaft 203 to rotate. When the transmission shaft 203 rotates, it drives the driven bevel gear 302 to rotate. The driven bevel gear 302 meshes with the driving bevel gear 301, causing the driving bevel gear 301 to rotate. The driving bevel gear 301 drives the drive shaft to rotate. The drive shaft drives the rotating shaft 104 to rotate. The rotating shaft 104 drives the rotating seat 105 to rotate. The rotating seat 105 drives the mounting bracket 106 to rotate, which in turn drives the photovoltaic panel 107 to rotate, realizing the adjustment of the angle of the photovoltaic panel 107. When the photovoltaic panel 107 is adjusted to the preset angle, the controller controls the servo motor 602 to stop running, completing the angle adjustment operation.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
